A bstract A simple test has been developed to measure the drying behavior of clays by noting the relative rate of flow of water through the clays as compared with the rate of evaporation from the surface. The addition of 0.2% of various chemicals to clays improved their drying properties. No one chemical was best for all of the clays, but the most effective chemicals varied in their reaction on different clays. Iron chloride exerted beneficial effect on most of the clays. A wetting agent, such as sodium chloride, hydrochloric acid, or soda ash, also improved the drying properties of certain clays.
